Specification of Letters Patent.

Application filedJuly 24, 1909. Serial no. 509,319.-

T 0 all whom 'it may concern:

Be it known that I, Jorm Gonnox' Coons, a citizen of the United States,residing at Chloride, in the county of Mohave and Terri tory of Arizona,have invented new and useful Improvements in Motor-Cooling Systems, ofwhich the following is, a specification.

This invention relates to internal combustion engines, the object inview being to provide an improved air cooling system by means of whichthe cylinders and valve casings and other parts connected with thecylinders may be effectively C(lOlQCl by a conand partly in section.-Fig. 2 is an enlarged plan view of the apparatus. Fig.3 is a frontelevation of the fan and fan casing. Fig. 4 is a front elevation of oneof the cylinders of the motor, showing a portion of the air coolingapparatus adjacent thereto includmg the oppositely located nozzles whichare shown in section. Fig. 5 is an inner face view of one of the nozzleson an enlarged scale.

Referring to the drawings, 1 designates the crank case of an internalcombustion motor and 2 the cylinders thereof. The motor is shown inFig'. 1 as mounted upon and used in connection with an automobile atwhich the front wheels are represented at 3.

4 designates the engine shaft provided with the usual fly wheel 5 andhaving mounted on its forward-end a sprocket wheel 6 from which a chain-7 runs around another sprocketwheel 8 on the shaft 9 of a fan orblower. The fan casing 10 which is best shown in Figs.2 and 3, comprisesoppositely arranged circular sections provided with flanges 11 adaptingthem to be bolted or otherwise secured together by suitable fasteners12. The forward section of the easing is provided with attaching lugs13, by means of which the fan casing may be secured to the frame of theautomobile or other machine. In the front of the casing there arearranged one or more air inlet apertures 14 to enable the air to besucked inward from the front of the machine through a suitable gratingor screen 15 taking the place of an ordinary" water radiator now incommon use.

The fan shaft 15 is mounted in suitable bearings 16 in'theoppositesections of the fan casing which bearings are lubricated by oil cups 17or any other convenient manner. The fan comprises a plurality ofradiating arms 18 to which areconnected blades 19 the outer ends ofwhich are preferably round as shownin Fig. l, the periphery of,

the fan-casing being also half round as shown at 20. At the top, the fancasing is provided with an outwardly and rearwardly extending elbow ordischarge outlet 21 to which is connected by means of. a union orcoupling 22 a trunk pipe 23 which extends backward over the tops of thecylinders 2, as clearly shown in Fig. 1 and indicated in Fig. 2. Justabove each of the cylinders 2 branch pipes 24 extend in oppositedirections from the pipe 23 and downward at opposite sides of thecylinders where the terminate in inwardly facing enlarged an flaringnozzles 25 each of which is formed with an elongated mouth 26, theelongation of the mouth being in the direction of length of thecylinder, as clearly indicated in Fig. 4. In this way, diametricallyopposite blasts of cold air are directed against corresponding points ofeach cylinder" of which the engine is composed, thus supplying to eachcylinder a separate and independent current of air at two diametricallyopposite points. The air thus directed against the cylinders is notconfined in any way but is liberated directly under the hood of theengine and is free to escape'immediately thereby allowin the fresh coolair to be constantly directe against each and all of the cylinders at aplurality of points.

The branch pipes 2st each side of the line of cylinders are connected bymeans of sec-- the rods in a manner clearly indicated in whenevernecessary, for the purpose of cleaning or taking down the engine, the.trunk pipe- 23 together with the branch pipes Fig; 2. The said-bracesare preferably connected at their forward ends to the front wall of thehood as shown at 31 while the rear ends thereof are connected to thedash boarder other convenient support as shown at 32. In this way, allof the branch pipes are-thoroughly braced and supported and 24 andbraces connecting said branch pipes may be readily removed by unscrewingthe coupling-22 and disconnecting the ends of the braces or studs fromthe dash board and j frontwall of the hood. The fan casing itself may beeasily unmounted when necessary by disconnecting the lugs 13- from themachine frame.

The air cooling apparatus is supported under the hood and is whollyindependentof the engine so' that removal of the engine or of thecooling apparatus can be efi'ected with t ease and despatch. Furthermorethe cooling 25 apparatus is in the nature of an attachment "which can beapplied to engines already in use as it does not enter into theconstruction of the engine, being entirely separated there from.

I claim In a motor vehicle, the combination ofan engine, a hood mountedover the engine and having an opening at its front, a fan mounted whollyon the hood at a point between the opening thereof and the front of theengine,

a conduit connected with the fan and extending rearwardl-y therefromover the top of the ing air directly through the'opening in the hood.

' In testimony whereof I afiix my signature I in presence of twowitnesses.

JOHN GORDON COOKE.
